BANDAeE-WINDING. MACHINE.,

T0 LZ/Z wiz/0m, it may concern:

Be it known that I, JOHN G. CRAWFORD, a citizen of the United States,residing at La Grange, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Bandage-findingMachines, of which the followinof is a full, clear,

concise, and exact description. e

My invention relates to a bandage-winding machine, and has for itsobject to provide a power-driven machine which will be easy to regulateand control and which will be capable of winding bandages withuniformity and great rapidity. I

My invention contemplates in general a bandage-winding machinecomprising a rotatable spindle, upon which bandages are to be wound, anda mot-or for operating the same, a standard supporting said motor andspindle, and mechanism carried by said standard for controlling andregulating the coperation of said motor and spindle -to regulate andvary the speed of the spindle. I thus provide a single and compactmachine by means of which an operator can wind bandages faster andbetter than has been possible heretofore, leaving both hands free tomanipulate the bandage.

My invention also contemplates an improved construction of thespindle-frame and winding-fingers whereby the bandage to be wound may bethreaded through the guidingfingers on the outside ofthe frame and movedto the interior of the frame and fastened to the spindle ready to bewound without requiring the end plate of the frame to be removed, as hasbeen necessary in the bandagewinding machines of the art.

I will describe my invention by reference to the accompanying drawings,wherein` Figure 1 is a front elevation of a bandagewinding machineembodying my invention. Fig. 2 is a detail end view of the spindleframe,showing the manner of threading a bandage through the guide-lingers.Fig. 3 is a plan view of the machine, showing the motor dotted in itsalternative position to vary the speed of the winding-spindle.

The same letters of reference are used to indicate the same partswherever shown.

The rotatable winding-spindle a. of the machine is arranged to be drivenby a motor b, carried by a supporting-standard c. The

said standard also serves to support the spin- Specification ofLettersPatent.

dle a, which may be provided with a drivingwheel a', mounted inoperativerelation to the friction-disk b, carried by the driving-shaft of themotor b. An arm d may be carried by the standard and serve as a supportor journal for the driving-wheel of the spindle,the said arm beingpreferably forked and the driving-wheel journaled between the twomembers d d thereof in position to engage The end plate e2 is slidablymounted upon the cross-bars e3 to adjust the frame to varying widths ofbandages and is adapted to be secured in any of its adjusted positionsby a suitable set-screw.

Fingers ff f2 are provided for guiding a bandage to be wound to thewinding-spindle, such bandage being passed or slipped between theguide-'lingers and connected with the spindle. Said fingers aresupported parallel to the winding-spindle at the edges of the two endplates, being preferably secured to the stationary end plate e. jectbeyond the adjustable end plate, which is cut away so as not to engagethe middle iingerf, said finger preferably extending a slight distancebeyond the ends of the outer fingers, which the end plate e2 aloneengages. It will thus be seen that to thread a bandage between theguide-fingers and connect the saine with the winding-spindle it issimply necessary to slip the bandage between the outer fingers andaround the middle nger, outside the end plate e2, and then move thebandage-loop along the middle finger into the interior ofthe frame, whenit may be fastened to the spindle a. This may be done without in any waydisturbing the adjustment of the end plate e2 or removing the same,which was necessary in winding-machines of the prior art.

Mechanism is carried by the supportingstandard c for. controlling andregulating the The ngers pro- IOC cooperation between the friction-diskb vand the driving-wheel a to regulate and vary the speed of thedriving-wheel and the windingspindle a driven thereby, or, in otherwords, to vary the speed of the driving-wheel without altering the speedo f the motor. To this end I preferably mount the motor l) in suolilmanner that it may be moved to vary the radial engagement of thefriction-disk b with'- the driving-wheel and so to increase or decreasethe speed of the rotating spindle. In the present instance the motor ismounted to turn on a vertical axis, as shown in dotted lines in Fig. 3,a spring in the base of the motor-frame serving to return the motor toits normal position. A treadle g is supported at the lower portion ofthe standard c, being preferably pivoted thereto, and is adapted whenoperated to turn the motor on its axis. The treadle may be connectedwith the motor by means of a chain h, extending through the hollow bodyof the standard and connected with one end of a lever i, pivoted to thestandard at the base of the motor, the other end of the lever beingconnected with the controlling-arm i of the motor, which is adapted whenoperated to close a circuit for the motor. and turn the same on itsaxis, a chain i2 preferably connecting the controlling-arm and lever i.

In the operation of the machine the adjustable end plate e2 is first setto adjust the frame to the particular width of bandage to be wound and abandage slipped through the guide-fingers ff f2, as previouslydescribed, and the end wrapped around the spindle. By operating thetreadle g the motor is started to drive the wheel a, the speed beingcontrolled by the extent of movement of the motor about its axis, asalready described. After the bandage is wound on the spindle into a rollthe operator grasps the spindle and gives it a turn in a directionreverse to that in which it is rotated by the motor to loosen theconnection of the banda e with the spindle, and the spindle may tiereupon be withdrawn and the roll removed. The bandage is hus woundevenly and tightly into a neat ro I claiml. In a bandage-windingmachine, the combination with a. rotatable winding-spindle, of a motorfor operating said spindle,
